Radiation Therapy Quality Assurance (RTQA) of Concurrent Chemoradiation Therapy for Locally Advanced Non-Small Cell Lung Cancer in the PROCLAIM Phase 3 Trial

Major violations in treatment plans were uncommon in the PROCLAIM study, possibly reflecting mandatory RTQA. The RTQA violations were more frequent in patients requiring more complex chemoradiation therapy plans. Poorer observed outcomes at centers with multiple major violations are hypothesis generating.
